The Boondocks You know that lethargic, sleepy feeling you get after a scrumptious large meal? Yeah, the itis is a mood, a scientific mood. The term is commonly referred to as the itis, which low key reinforced the "lazy" stereotype in the Black community. Which is hardly the case. The scientific term for this phenomenon is referred to as postprandial somnolence. Just like the term, hangry, it's all science.
